| 2 | fdkaac - command line frontend encoder for libfdk-aac |
| 3 | ========================================================================== |
| 4 | |
| 5 | Prerequisites |
| 6 | ------------- |
| 7 | You need libfdk-aac. |
| 8 | On Posix environment, you will also need GNU gettext (for iconv.m4) and |
| 9 | GNU autoconf/automake. |
| 10 | |
| 11 | How to build on Posix environment |
| 12 | --------------------------------- |
| 13 | First, you need to build libfdk-aac and install on your system. |
| 14 | Once you have done it, the following will do the task. |
| 15 | (MinGW build can be done the same way, and doesn't require gettext/iconv) |
| 16 | |
| 17 | $ autoreconf -i |
| 18 | $ ./configure && make && make install |
| 19 | |
| 20 | How to build on MSVC |
| 21 | -------------------- |
| 22 | First you have to extract libfdk-aac source here, so that directory tree will |
| 23 | look like the following: |
| 24 | +- fdk-aac ---+-documentation |
| 25 | | +-libAACdec |
| 26 | | +-libAACenc |
| 27 | | : |
| 28 | +- m4 |
| 29 | +- missings |
| 30 | +- MSVC |
| 31 | +- src |
| 32 | |
| 33 | MSVC solution for Visual Studio 2010 is under MSVC directory. |
| 34 | |
| 35 | Tagging Options |
| 36 | --------------- |
| 37 | Generic tagging options like --tag, --tag-from-file, --long-tag allows you |
| 38 | to set arbitrary tags. |
| 39 | Available tags and their fcc (four char code) for --tag and --tag-from-file |
| 40 | can be found at http://code.google.com/p/mp4v2/wiki/iTunesMetadata |
| 41 | |
| 42 | For tags such as Artist where first char of fcc is copyright sign, |
| 43 | you can skip first char and just say like --tag="ART:Foo Bar" or |
| 44 | --tag-from-file=lyr:/path/to/your/lyrics.txt |
